First, a caveat: according to most experts, the biggest challenges with weather data are related to issues of data availability, discoverability, quality, coverage and documentation; the lack of standardization is a challenge but less impeding than the above.

Both for weather data and for farm management data, standardization of variable names across the different communities and even within the same community is an issue. Some work has been done, from the Climate and Forecast Metadata Convention designed for NetCDF to the publication of BUFR and GRIB codes in RDF, but there is no naming convention that is universally used, nor mappings or cross-walks between variables used in different systems.

Generalizing the issue above, there are many different code lists used by different authorities (e.g. EU, WMO, Met Offices). Some correspondences / mappings have been developed, but mostly ad hoc for specific platforms and not in a reusable way.

Given the varied landscape of data providers and related formats, intermediaries still have to do most of the work converting, processing, re-purposing the data between the different steps in the data value chain.

Besides the official WMO network, many different platforms have been created for different consumers (researchers, FMIS developers, weather service developers, farmers, journalists) with very different data outputs.

Some experts noted that there is no way yet to use standards to clarify and enforce data rights and data ownership at each stage of the data value chain.

Based on this gap analysis as well as a “developer experience” review based on the farm management use case, we put together a set of key recommendations.

1) Using standards to improve discovery

This is in answer to the challenge regarding discoverability of data, which in terms of use of data standards could be improved by:

This is in response to the issue of variety of formats used and the lack of documentation and clarity about formats and standards, which could be improved for different users:

for data publishers, provide a detailed evaluation and comparison of the existing formats with guidance on when and where to use them to publish data, and which conventions are useful;

for non-specialist data consumers, provide good introductory guidance on how to parse and use specific data formats within modern frameworks;

for both publishers and consumers, invest in open source tooling, e.g. parsers, validators and converters, to help developers publish and use the data;

creating some community support: e.g. explore third-party, community-led supporting activities, e.g. Question & Answering (Q&A) Services, to help data publishers identify relevant standards and understand how to apply them in the publication of their data and to connecti standards authors with the communities that publish and consume data.

3) Usability of standards: shared and linked vocabularies

This is in answer to the challenge of having many different code lists and no agreed lists of variables; work could be done to improve this, e.g.:

Identifying 2-3 key code lists that should be published in more linkable, versatile formats, at an authoritative domain (e.g. Climate and Forecast Convention, BUFR/GRIB codes, ICASA variables, AgGateway variables…).

Linking key code lists and providing web services for cross-walks.

Both the gap analysis and the recommendations will be soon published.

Work in the Standards focal area will now continue towards a) transforming the recommendations into technical specifications and then into pilot services; b) following the same cycle for the two new thematic topics selected by the project: nutrition data and land data.
